基于起动发电一体机的车用混合动力总成控制策略研究

针对未来军用混合动力车辆的需求，设计了一种基于起动发电一体机（ISG）电机的高功率密度混合动力总成方案，制定了相应的基线式控制策略。在基于ADVISOR构建的后向仿真模型中，以某型轻型越野车辆参数以及混合动力总成的参数作为仿真输入条件，分析了动力总成对车辆动力性能和燃油经济性的影响。仿真结果表明：基于ISG电机的混合动力总成扭矩输出值与原车发动机相比获得较大提升；同时优化了发动机工作点，降低了发动机油耗，提升整车的燃油经济性。

Study of Control Strategy for Power Train Based on ISG Hybrid System

A high density power-train system based on ISG motor is designed for the future military hybrid vehicles, and the structure of the system is designed. The line-based control strategy of the power-train system is established，and also the control objectives and working mode are divided. A backward-simulation model of ISG hybrid system based on ADVISOR is established. The performance of ISG hybrid system based on the parameters of a subsection ISG motor and diesel engine is simulated. The result shows that the power-train system can improve the torque characteristic greatly, and enhance the torque ratio-t ranges. The power-train system can also optimize the working points of engine to reduce the average fuel consumption rate of diesel engine.
